Enum WalError 

pub enum WalError {
    ChecksumMismatch {
        entry_seq: u64,
        expected: u64,
        got: u64,
    },
    CorruptedEntry(u64),
    TransactionNotFound(u64),
    EntryTooLarge(usize),
    SegmentFull,
    InvalidMagic,
}

Errors returned by WalWriteAheadLog operations.

Variants

ChecksumMismatch

A decoded entry’s checksum does not match the computed value.

Fields

entry_seq: u64

expected: u64

got: u64

CorruptedEntry(u64)

The entry’s byte representation is malformed.

TransactionNotFound(u64)

No transaction with the given id is tracked.

EntryTooLarge(usize)

The encoded entry exceeds the configured maximum.

SegmentFull

The segment buffer is full.

InvalidMagic

The four-byte magic header is invalid.

Trait Implementations

impl Clone for WalError

fn clone(&self) -> WalError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for WalError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for WalError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for WalError

impl Error for WalError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for WalError

fn eq(&self, other: &WalError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
